Technical Field
[0001] The present invention relates to the technical field of magnetic steel pressing equipment, and in particular to a new energy motor built-in rotor magnetic steel pressing equipment. Background Art
[0002] The rotor is a key component in the motor, and its manufacturing process directly affects the overall quality of the motor.

If the edge of the magnetic steel is damaged, the gas leaks from the crack, and the hollow ball cannot move up. The trigger mechanism marks the damaged position, automatically detects the damage of the magnetic steel edge, and uses gas to push the hollow ball to reduce wear.
[0026] When the detection mechanism has completed the detection, the contact piece withdraws from the magnetic steel slot, and the ejection mechanism rotates to the position of the magnetic steel slot marked with a defective magnetic steel slot, and pushes the damaged magnetic steel out of the magnetic steel slot.

[0027] A partition is added inside the contact piece. When the contact piece moves to the damaged part of the magnetic steel, the gas enters the air inlet cavity from the connecting pipe, and some gas leaks out from the rupture. The gas enters the airbag through the air pipe, the airbag inflates and becomes larger, and the air inlet of the L-shaped tube shrinks, reducing the amount of air intake. The reduced thrust causes the hollow ball to fall quickly and release the contact with the trigger mechanism, quickly triggering the reaction time of the trigger mechanism.
[0028] When the hollow ball falls, the connecting ear will stop it from falling further. If it encounters a damaged position, the gas thrust is not enough to push the hollow ball up, and the hollow ball made of conductive metal will contact the electrode sheets on both sides of the connecting ear, thereby connecting the circuit and judging that the magnetic steel in the magnetic steel slot is damaged. The circuit connection can achieve rapid judgment and improve detection efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0041] In order to better understand the internal rotor magnetic steel pressing device of a new energy motor provided in the embodiment of the present application, the existing magnetic steel pressing device is briefly introduced below. First, the rotor is fixed on a special fixing seat to ensure that it will not move during the pressing process. The magnetic steel is usually placed on a fixture or a supporting device to ensure that the magnetic steel is accurately positioned so that the press can accurately press it into the rotor magnetic steel slot. The pressing device, such as a hydraulic cylinder or a servo motor driven pressure head, moves along a predetermined path and gradually approaches the magnetic steel. When the pressure head contacts the magnetic steel, it will continue to apply pressure to slowly but forcefully push the magnetic steel into the magnetic steel slot in the rotor. If manual installation is adopted, the rotor is fixed on a plane and the magnetic steel is pressed by fingers to press the magnetic steel into the magnetic steel slot in turn. The side walls and edges of the magnetic steel are usually the most vulnerable points, and tiny cracks may occur during the manufacturing process. Therefore, during use, when pressing, clamping or fixing, the edge part may be subjected to greater concentrated stress, thereby causing cracks. In particular, after the magnetic steel is pressed into the magnetic steel slot of the rotor, it is not possible to directly observe whether the edge of the magnetic steel is cracked;
[0042] The following is a brief overview of the present application. After all the magnets are pressed into the rotor magnet slots by the press-fitting equipment, the magnet edges are inspected. If a damaged magnet is found, the magnet slot where it is located is marked and it is pushed out and re-pressed until the product is qualified. This process is completed before the press-fitted rotor is placed in the motor to avoid problems that are difficult to remedy after being installed in the motor.
[0043] Example 1: Please refer to Figure 1-10 The present invention provides a technical solution: a new energy motor built-in rotor magnetic steel press-fitting device, comprising:
[0044] The press-fitting mechanism 10 comprises:
[0045] A workbench, both sides of which are fixedly connected to a press-fitting table, a magnetic steel filling mechanism is arranged inside the press-fitting table, an electric cylinder three is fixedly connected to the press-fitting table, a pressure head is fixedly connected to the end of the telescopic rod inside the electric cylinder three, and the electric cylinder three cooperates with the magnetic steel filling structure to press the magnetic steel into the rotor magnetic steel slot. The above are all prior arts and will not be elaborated on here;
[0046] A mobile base 20, wherein a servo motor 22 is disposed at the bottom of the mobile base 20, and a housing of the servo motor 22 is fixedly connected to the bottom of the mobile base 20, and the mobile base 20 is used to cooperate with the press-fitting mechanism 10 to press the magnetic steel into the rotor magnetic steel slot;
[0047] A rotor fixing seat 21, wherein the rotor fixing seat 21 is fixedly connected to the end of the internal rotating shaft of a servo motor 22;
[0048] It should be noted that by placing the rotor on the rotor fixing seat 21, the rotor fixing seat 21 is used to fix the rotor to prevent it from shifting during the press-fitting and testing process. After the movable base 20 is moved to the bottom of the press-fitting table, the pressure head at the bottom of the electric cylinder 3 presses the magnetic steel into the rotor magnetic steel slot, and then the movable base 20 moves the rotor to cooperate with the rotor fixing seat 21 to be directly below the testing mechanism 30;
[0049] The detection mechanism 30 includes:
[0050] An air pump 31, wherein a shell 32 is provided at the bottom of the air pump 31, wherein the top of the shell 32 is connected to the air outlet of the air pump 31, wherein a plurality of connecting tubes 33 are connected to the bottom of the shell 32, wherein a contact member 34 is provided at the bottom of the connecting tube 33, wherein the top and bottom of the connecting tube 33 are respectively connected to the shell 32 and the contact member 34, wherein one side of the contact member 34 is an open end, wherein the open end of the contact member 34 is in contact with the side wall of the magnetic steel, wherein the top side wall of the connecting tube 33 is connected to an L-shaped tube 35, wherein the top of the L-shaped tube 35 is an open end, wherein a hollow ball 36 is provided in the straight section of the L-shaped tube 35, wherein a trigger mechanism 37 is provided on the straight section of the L-shaped tube 35, wherein the top of the L-shaped tube 35 is in the shape of a trumpet;
[0051] It should be noted that after the rotor with the inserted magnetic steel is moved to the lower side of the detection mechanism 30 in cooperation with the rotor fixing seat 21, the contact piece 34 at the bottom of the connecting tube 33 is inserted along the gap between the magnetic steel and the magnetic steel groove, with the open end of the contact piece 34 facing the edge of the magnetic steel. When the contact piece 34 is completely immersed in the magnetic steel groove, the air pump 31 starts to supply air. If the edge of the magnetic steel is not damaged after insertion, the open end of the contact piece 34 will fit and seal with the edge of the magnetic steel, so the air will pass through the L-shaped tube 35 to reach the position of the hollow ball 36. When the thrust generated by the air is greater than the gravity of the hollow ball 36, the hollow ball 36 moves upward along the L-shaped tube 35, and the hollow ball 36 reaches the top of the L-shaped tube 35. When the L-shaped tube 35 is opened, the gas will be released from the edge of the hollow ball 36, so the hollow ball 36 will be in a floating state at the top. If the edge of the magnetic steel is damaged during the insertion of the magnetic steel slot, as the connecting tube 33 drives the contact piece 34 to move along the edge to the damaged position, a gap will be generated at the open end of the contact piece 34, and the gas generated by the air pump 31 will leak from the crack between the contact piece 34 and the magnetic steel. At this time, the amount of gas entering the L-shaped tube 35 will be reduced, and the thrust generated by the gas will not be enough to push the hollow ball 36 upward. When the hollow ball 36 contacts the trigger mechanism 37 on the L-shaped tube 35, the trigger mechanism 37 will cooperate with the terminal to mark the magnetic steel slot at this location.
[0052] The ejection mechanism 40 is disposed on the upper side of the rotor fixing seat 21 and is used to cooperate with the detection mechanism 30 to eject the defective magnetic steel from the rotor magnetic steel slot;
[0053] It should be noted that, after the detection mechanism 30 has completed the detection, the contact piece 34 withdraws from the magnetic steel slot, and the ejection mechanism 40 rotates to the position of the magnetic steel slot marked with a defect, and pushes the damaged magnetic steel out of the magnetic steel slot. With this design, the integrity of the magnetic steel can be detected after the magnetic steel is installed in the magnetic steel slot, thereby avoiding the overall scrapping of the workpiece after directly installing it into the motor, and reducing the scrap rate to a certain extent.
[0054] Further as Figure 4 , Figure 5 and Figure 7As shown, it is worth to explain in detail that a partition 341 is provided in the contact member 34, and the partition 341 is fixedly connected to the inner wall of the contact member 34, and the partition 341 divides the contact member 34 into an air outlet cavity 342 and an air inlet cavity 343;
[0055] It should be noted that by adding a partition 341 in the contact member 34, when the contact member 34 moves along the edge of the magnetic steel, when the partition 341 moves to the damaged position, the gas in the connecting tube 33 will pass through the air cavity 342 and then enter the air inlet cavity 343 through the gap between the partition 341 and the damaged position of the magnetic steel, or partially enter the air inlet cavity 343 and partially directly flow out from the ruptured position of the magnetic steel and enter the air inlet cavity 343;
[0056] An air pipe 344, the lower end of which passes through the contact member 34 and communicates with the air inlet cavity 343, the upper end of which passes through the L-shaped pipe 35, and the top end of which is connected to an air bag 345;
[0057] It is worth noting that the gas enters the airbag 345 through the air pipe 344 connected to the air inlet chamber 343, and the airbag 345 becomes larger when filled with air. Since the airbag 345 is arranged in the L-shaped tube 35, when the airbag 345 increases, the cross-section of the air inlet of the L-shaped tube 35 decreases, thereby reducing the air intake volume in the L-shaped tube 35. At this time, the thrust generated on the hollow ball 36 will decrease rapidly, causing the hollow ball 36 to fall quickly and release from the trigger mechanism 37. In this way, the reaction time of starting the trigger mechanism 37 when the damaged part of the magnetic steel is detected can be improved.
[0058] Further as Figure 7 As shown, it is worth to explain in detail that the edge of the opening end of the contact member 34 and the edge of the partition 341 are both attached with a rubber strip 346;
[0059] It should be noted that by attaching the rubber strip 346 to the edge of the opening end of the contact piece 34 and the edge of the partition 341, the rubber strip 346 can increase the sealing performance between the contact piece 34 and the partition 341 and the edge of the magnetic steel, thereby making the detection more accurate.
[0060] Further as Figure 7 As shown, it is worth to explain in detail that the trigger mechanism 37 includes:
[0061] Connecting ears 371, the connecting ears 371 are fixedly connected to the inner wall of the straight section of the L-shaped tube 35, the connecting ears 371 are symmetrically arranged in two groups, the top of the connecting ears 371 is arc-shaped, the upper surface of the connecting ears 371 is provided with an electrode sheet 372, and the hollow ball 36 is made of conductive metal;
[0062] It should be noted that when the hollow ball 36 falls, the connecting ear 371 can prevent the hollow ball 36 from continuing to fall. When encountering a damaged position, the thrust generated by the gas is not sufficient to push the hollow ball 36 upward. When the hollow ball 36 made of conductive metal contacts the electrode sheets 372 on the connecting ears 371 on both sides, the circuit is connected at this time, and it can be determined that the magnetic steel in the magnetic steel slot here is damaged.
[0063] Further as Figure 7 As shown, it is worth noting that a barrier net 351 is provided at the top open end of the L-shaped tube 35;
[0064] It should be noted that, by fixing the barrier net 351 on the top of the L-shaped tube 35 , when calibrating whether the hollow ball 36 reaches a balanced state in the L-shaped tube 35 , the barrier net 351 can be ventilated and prevent the hollow ball 36 from flying out of the L-shaped tube 35 .
[0065] Further as Figure 2 , Fig. 9 and Fig.10 As shown, it is worth to explain in detail that the ejection mechanism 40 includes:
[0066] A rotating disk 41, on which an electric cylinder 42 is disposed, a housing of the electric cylinder 42 is fixedly connected to the rotating disk 41, a push plate 43 is fixedly connected to the end of the telescopic shaft inside the electric cylinder 42, and the push plate 43 is used to cooperate with the electric cylinder 42 to push the magnet out of the rotor magnet slot;
[0067] It should be noted that after the detection mechanism 30 completes the detection, the rotating disk 41 drives the electric cylinder 42 to rotate to the top of the magnetic steel slot with the damaged magnetic steel, and the electric cylinder 42 drives the push plate 43 to push the damaged magnetic steel in the magnetic steel slot out of the magnetic steel slot, and then the moving base 20 drives the rotor fixing seat 21 to move to the pressing table to re-press the magnetic steel.
[0068] Further as Fig. 9 As shown, it is worth specifically explaining that an arc-shaped disc 51 is provided on one side of the detection mechanism 30, and the arc-shaped disc 51 is fixedly connected to the end of the telescopic rod inside the electric cylinder 2 52, and the electric cylinder 2 52 is provided on the top of the arc-shaped disc 51, and the outer shell of the electric cylinder 2 52 is fixedly connected to a fixing frame 53, and the fixing frame 53 is fixedly connected to the surface of the workbench, and the fixing frame 53 is used to fix the electric cylinder 2 52, and the bottom of the arc-shaped disc 51 is fixedly connected to the outer shell of the air pump 31, and the air pump 31 is provided with several groups;
[0069] It should be noted that by driving the arc disk 51 to move up and down along the rotor magnetic steel slot through the electric cylinder 2 52, the contact member 34 can be driven to slowly detect along the edge of the magnetic steel. At least three groups of air pumps 31 are provided. By providing multiple groups of air pumps 31, the purpose of simultaneously detecting the edges of magnetic steels in multiple magnetic steel slots can be achieved, thereby increasing the detection efficiency to a certain extent.
[0070] Further as Fig. 9 As shown, it is worth specifically explaining that the rotating disk 41 is rotatably connected with the telescopic rod inside the electric cylinder 2 52, the inner wall of the rotating disk 41 is provided with teeth 61 in a circumferential array, the surface of the arc disk 51 is provided with a servo motor 2 62, the outer shell of the servo motor 2 62 is fixedly connected to the arc disk 51, and the end of the rotating shaft inside the servo motor 2 62 is fixedly connected with a gear 63, and the gear 63 is meshed with the teeth 61 on the inner wall of the rotating disk 41;
[0071] It should be noted that after the detection mechanism 30 has detected the magnetic steel slots on one side of the rotor, it will detect the magnets in the magnetic steel slots on the other side. At this time, the servo motor 2 62 will drive the rotating disk 41 to rotate through the top gear 63 until the electric cylinder 1 42 on the rotating disk 41 moves to the magnetic steel slot with the damaged magnet. The electric cylinder 1 42 will cooperate with the push plate 43 to push the damaged magnet out of the magnetic steel slot until there is no damaged magnet in the detected magnetic steel slot.
[0072] Further as Fig.10 As shown, it is worth explaining in detail that a circumferential array of through slots 71 is opened on the rotor fixing seat 21, and the number of the through slots 71 is equal to the rotor magnetic steel slots. When the electric cylinder 1 42 drives the push plate 43 to push the damaged magnetic steel, the damaged magnetic steel will be discharged out of the magnetic steel slot through the through slots 71 on the rotor fixing seat 21.
[0073] Further as Fig.10 As shown, it is worth explaining in detail that a placement tray 81 is fixedly connected to the top of the movable base 20, and the placement tray 81 is used to place magnets. An insert plate 82 is slidably connected to one side of the placement tray 81, and the discharged broken magnets will fall into the placement tray 81. When the placement tray 81 is full, the insert plate 82 can be pulled out to recover the broken magnets.
[0074] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
[0075] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, all of which fall within the scope of protection of the present invention.
